PRESSED-STEEL WINDOW SILL.

"Application med January s, 1922. seriai No? 527,306.

T 0 all whom t may concern:

Be it known that I, GEORGE W. BROOKS, a citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Pressed-Steel Window Sills, of which the following is a specilication.

This invention relates to certain new and useful improvements in window-sills of that general class formedy of metal as a substitute for stone, cement or wooden sills, and it has for its objects among others to provide a simple, cheap, durable and efficient window fsill, preferably, although not necessarily, of pressed steel, constructed and shapedto fill the same space as previously occupied by the stonev or other form of sill, and at the same time adapted to permit of the passage of fresh air through the sill into the room where it may be delivered to any desired point, as directly above the radiator, or wherever it may be found most expedient.d

The sill is preferably equipped with a controlling device, and means for preventing the ingress of flies and insects. The Ventilation section may occupy a greater or less -length of the sill, and the sill may be cut in sections with joints coming under the mullions in the window opening. Where more than one window is used, the Ventilating apparatus may betset in one or all sections of the sill, and the same may be closed all or part of the time, as may be desired. The construction may be suoli that fresh air may be' conducted from the Ventilating sill into the floor or through the floor to the ceiling of the room underneath the said floor.

In fact, the invention is'capable of embodiment in a Variety of forms, some .of the preferred ones only of which are herein illustrated.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention, in such preferred forms, is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which Figure l isa Vertical section showingone of Jmy improved sills with the outlet just above the base of the room.

Figure 2 is a Vertical section showing a 45 outlet.

Figure 3 is a similar View, showing a modified form of outlet.

Figure 4 is an enlarged elevation of the exterior of a window, showing the air inlet openings.

' Figure 5 is a section on the line 5-5 of Figure 4`r looking in the direction of the arrows.

Figure 6 is a perspective detail of one end of a sill section and a gasket.

Figure 7., is a perspective View of the sill looking at the exterior.

Like numerals of reference indicate like parts throughout the different views.

Referring to the drawings,

1 designates the sill, as a whole, in all of its forms, it being understood that the primary object is to insure4 a supply of fresh air into the room.

It is well known that the unhealthful condition of foul air in congested or close quarters, such as sleeping compartments on trains or other places where bodies congregate, is harmful and injurious.

'This new and useful method of Ventilating gives a sufficient quantity of fresh air in crowded and often-used rooms, inistationary meeting places, as well as when traveling on trains and the like, allowing the windows to be closed, fastened or securely locked by standard methods, meanswhile permitting a supply of fresh air into any place desired. The ventilator sill can be used for a sill course or asv a substitute for terra cotta, stone, etc.

It provides a neat and eflicient method of Ventilating.

It is sightly, artistic, and convenient of access. Ventilation'is at the window opening, or elsewhere, if desired. Ventilation can eX- tend the full width of sill or a small section can be Ventilated.

Regulation of the quantity of air used can be had mechanically or can be thermostatically controlled. Any known `building material, particularly any gauge of metal, may

The natural place or location for` bflused in the construction of this ventilated s1 '.llhe sill and its appurtenances are built into the masonry or structure and become an integral part of the building. lt can be made in standard sections and fastened toether. When apparatus is used at the winow, a bearing plate can be applied at each end or a panel can be formed on the surface of the sill.

llt can be made weather-proof by any of the well-known methods of weather-proofing. Comparatively a light weight apparatus, it is easy to handle and install. lt reduces cost of transportation. llt is everlasting and non-breakable.

llt can be used with or without ventilation attachment. on the sill can 4be used for ornamental eti'ects. The ventilation louver and valve or damper, as shown, to the vent outlet 4in the room is a standard type of grille and damper which may be of any make damper as sold on the market at the present time, and ll will have it understood that I do not confine my invention to any particular form of interior grille or damper and device for controlling the air into the room as my invention relates `more particularly to the sill and appearance from the exterior, hence the details of construction of interior ventilating grille and damper control are immaterial.

In all of the forms the main portion of the sill is rolled or shaped to the same form as the Stone sill, having a lug 2 forming a weather bar located in a recess 3 in the wood sill 4, and having an upwardly inclined inturned member 5, which as shown clearly in Figures l, 2 and 3, extends upward and inward into the space 6 between the courses of stone 7, where, if desired, it may be embedded in the mortar joint. This main section has its upper surface inclined, as seen at 8, to form a sloping window stool. The inclined member 5, at its lower end, is provided with one or more openings 9 bored from the under side into the tapered channel, as clearly shown in Figure 1 so that any moisture or condensation reaching the inside of the sill through t-he perforations 10 in the front face thereof, will immediately drain 0H' through such openings. Furthermore, the drip thus formed constitutes the correct water drip, as usually required in stone sills.

The interior hollow space 11 formed by the hollow member l2 constitutes the vent vent section 12 is designed to be covered.

by hardware wire, cloth, copper Hy screengethen Various designs of ventilator4 Malacca holes 16, as shown, for the reception of bolts 17 whereby the sections may be bolted to- @iaskets 18, of lead or other suitable material, about one-sixteenth of an inch in thickness, as seen in Figure 6, and provided with holes 19 for the passage of the bolts, are disposed between adjacent ianges of the sections, being preferably coated with suitable material, as white lead putty, before the bolts are drawn tight so as to make the joint thoroughly waterproof.

'llhe sill is usually supplied with one coat of paint at the factory, and can afterwards be painted to match any color of trim either in stone or terra cotta.

The socket or recess 3 in the under side of the wood sill which receives the upturned member 2 should be calked with waterproof cementor the like.

'llhe shape andangle of the vent outlet may vary to suit Varying conditions or wishes of the builder. For instance, in Figure 2 it is shown as extended at an angle of about 45 and its inclined end 20 is provided with a reticulated closure 21, While in Figure 3 the outlet extends inclinedly, as at 22, and thence horizontally, as at 23, and is provided with the vertical closure 24 having suitable openings, as seen at 25. So the vent outlet ma be made tosuit varying conditions. In Figure l it is shown as terminating in a downwardly-extended duct 26 opening laterally into the room adjacent tirely. For this purpose I have shown in the present instance a member 29 pivoted in any suitable manner, at 30, and adapted to be operated when desired by means of a control wheel 3.512, as indicated in Figures 1, 2' and 3.

At the left in Figure 4 the end of the s'ill is shown as built into the masonry work. rllhis sill is to project four inches out into masonry work from edge ofthe Window opening. rlhe end of this sill is to be turned back at a ninety degree angle and to have welded corners, the turned back surface to run at least two inches in to the wall. 32 is a cast iron lug laid on top of the sill' and attached with two countersunk` vscrews 33, the same covered back under masonry wall. rll`his lug provides. the ordinary built up lug as 'used withstone sills. This lug mayor may not be used lwith sill as'the 'space required for same may be taken up in -a mortared Joint.

I have ldevised a metallic .ventilating ,sill

that will fill all the requirements, and one* that can be manufactured at comparatively 4- small cost, as well as vrequiring unskilled labor to assemble. and put in place, and while the structural embodiment of my invention as hereinbefore described is what l, at thel present time, consider preferable, it is evident that the same is subject to changes, variations and modificationsy in ldetails of construction, proportion of parts, etc., without departin from the spirit of the invention or sacri ing any of its advantages. l, therefore, do not intend to restrict myself to the exact lconstruction, ar-

rangement andA proportion of parts, as here inbefore disclosed, but reserve the right to.

make such changes, variations and modifications as come properlywthin lthe scope.V
